CARDING MACHINERY.

Application filed May 5,

As is well known, cotton carding machines have to be stripped from twoto four times per day depending on the amount of cotton carded per dayand the grade of the same in order to do good carding. When stripping acard you stop the cotton in lap form from feeding into the machine andproceed to strip the cylinder and doffer by means of stripping rolls ora vacuum stripping system of all cotton and other foreign matter whichhas become embedded in the wire cloth on the cylinder and dofi'er.Heretofore in the art after the stripping operation has been completedthe feed roller is started so that the cotton lap is fed into the cardwherein the cotton fibres are combed or carded and are delivered bymeans of the doffer or coiler head into a can which is placed in frontof the machine. It has been found however that when starting the machineup after the stripping op eration the weight per yard of the first fewyards of sliver is very light owing to the fact that a great deal of thecotton which is fed into the machine is being pressed into the wireclothing of the cylinder and thus is utilized to charge the cylinder andis not taken therefrom by the doffer. As soon as the cylinder fills upor has become charged the weight per' yard of the sliver taken therefromby the doffer reachesthe average weight for which the machine is set toproduce but this correct average weight is not produced until aboutfifty yards of sliver has been delivered from the machine after thestripping operation. Such light weight and non-uniform sliver makes veryuneven and a very poor grade of yarn. For example, it has been foundthat where the average weight per yard of the sliver pro duced underordinary operating conditions before stripping was fifty-nine grainswith a variation in weight of four grains per yard, the weights rangingfrom fifty-seven 1923. Serial 3T0. 636,917.

to sixty-one grains per yard on a sixty-yard test then after strlppingcard machine, the

first yard delivered weighed thirty-two grains and forty-eight yardswere delivered before the machine reached fifty-eight grains. It will benoted from these findings that'the first yard delivered after thestripping operation with the ordinary machine will run about forty-fiveper cent light.

The object of the present invention is to provide an automatic sliverevener adapted to be oragnized with carding machines and which when soorganized is effective to overcome the aforementioned difficulties anddisadvantages and to enable the carding machine to produce a uniform andhighgrade' product as well immediately after the stripping operation asdurmg normal operation.

For instance wlth the same mach ne whose performance has been notedabove but after havin OI dIIlZGCl therewlth the automatic sliver evenerconstituting the present inven:

tion, the weight of the first yard delivered after the strippingoperation was found to be sixty grains with a variation in weight peryard of two and one-half grains in a twenty yards test, the lightestweight per yard being fifty-seven and onehalf grains.

" hen the automatic sliver evener constituting the present invention isin' use the weight per yard runs more evenly immedl V-ately afterstripping than it does with the ordinary machine ordinarily equippedwhen operating under normal conditions.-

A further object is to provide a device of this character, and havingthe foregoing advantages and which is also of simple and durableconstruction, reliable and efficient in operation and adaptedto beorganized with;

conventional card'ag machinery without.

necessitating serious or. expensive .altera tions.

Other objects and advantages of the invention reside in certain novelfeatures of the construction, combination and arrangement of parts whichwill be hereinafter more fully described and particularly pointed out inthe appended claims, refer: ence being had to the accompanying drawingsforming part of this specification and in which: 7 1 Figure 1 is adiagrammatic view, in plan, showing the relation of the automaticsliverevener constituting the present invention-to certain of the machine;

Figure 7 is a detail view illustrating the connection of the hand leverand sleeve of the automatic shifting mechanism.

Referring to the drawings it will be seen that the carding machine isshown diagrammatic'ally and it is to be understood that it may be of anyconventional construction. In the drawings it is shown as including aframe 5 upon which is mounted and suitably driven a main cylinder 6; Atthe rear end of the machine is a lickerin 7 and a feed roller 8 andatthe front end of the machine and cooperating with the main cylinder isa doffer 9; The main cylinder, licker-in, feed roller and doifer haveshafts 10, 11, 12 and 13, respectively, which it is to be understood aresuitably journaled on the frame 5 and project at their ends beyond theframe.

The licker-in 7 is driven from the shaft 10 of the main cylinder 6 by across belt 14 trained over pulleys fixed to the shafts 10 and 11. Meansis provided for driving the doffer from the licker-in and includes agear Wheel 17 secured to the shaft 13 and adapted to be driven from apinion 18 fixed to one end of a short shaft 19. The short shaft 19 isrotatably mounted in a bearing prov ded in a depending bracket 20integral with a Vertically swinging arm 21 on one end of which arm 21.is pivotally. mounted, as at 22, on the frame 5. A hand lever 23 issuitably mounted on a bracket 24 and cooperates with the free end of thearm 21 and controls its position and incidentally controls theengagement or disengagement of the pinion 18 and gear wheel 17. Theshort shaft 19 which has fixed thereto the pinion 18 also has fixedthereto a pulley 25 driven by a belt 26 from the licker-in. Thisarrangement thus far described is conventional and standard in allrespects.

'Means is provided for driving the feed roll from the shaft 13 of thedoifer cylinder when desired and preferably the feed roll is driven fromthe shaft 13 of the doffer cyl inder at all times except during theperiod which follows immediately after the stripping. For this purpose ashaft 30 is pro vided and has one end geared, as at 31, to the shaft 12of the feed roller 8. ()n the opposite end of the shaft 30 from thatwhich is geared to the feed roll 8 a sleeve is mounted so as to be atall times constrained to rotate with the shaft 30 while free to beshifted longitudinally or axially with respect thereto. In order toefiect this mounting (see Figure 3) the sleeve 32 is slottedlongitudinally, as at 33, and in the slot 33 a pin 3% is received, thepin 3% being fixed to the shaft 30. Obviously other means may beemployed for so mounting the sleeve 32 on the shaft 30. One end of thesleeve has secured thereto a beveled gear wheel adapted to be broughtinto mesh with a coacting beveled gear wheel 36 fixed to the shaft 13 ofthe doii'er cylinder on the end of this shaft 13 opposite from the ringgear 17. When the gears 35 and 36 are in mesh the feed roll 8 is drivenfrom the doifer 9. l/Vith the present invention it is proposed to drivethe feed roll independently of the doii'er immediately after thestripping operation, the doifer being allowed to remain stationarywhereby the main cylinder may be charged or filled up to the requisitedepth to obtain sliver of proper weight. In order to carry out thesepurposes a large gear wheel 38 is also fastened to the sleeve The gearwheels 35 and 38 are spaced from each other and their hubs 35Pand 38"define an annular groove 37 between them, the function of which willhereinafter fully appear. hen the sleeve 32 is shifted in one directionon the shaft 30 as for instance to the left as viewed in Figure 3, thebeveled gears 35 and 36 will be disengaged and the large beveled gear 38will be brought into engagement with a small beveled gear 39 fixed to avertical shaft 4-0 adjacent the upper end thereof. The vertical shaft 40is mounted at its lower end in a spindle bear ing 41 and at its upperend it is rotatably mounted in a bearing 42 provided in a bear ingbracket 43 secured to the frame 5, as shown in Figures 3 and 4. Thevertical shaft 40 is driven from a jack shaft 45 extendingtransverselyacross the machine by beveled gears 16 to provide for aspeed reduction, the jack shaft 15 being held for rotating movement, asat 47', in the frame and carrying at its end opposite the vertical shaftaw a large spur gear wheel 48 wh ch is so disposed that the pinion 18 isadapted to be brought into mesh therewith. It will thus be understoodthat the pinion 18 is selectively engageable with either the gear wheel17 of the doifer cylinder or with the spur gear wheel 48 of the jackshaft so that the motion received by the pulley 25 from the belting 26may be transmitted to the doffer cylinder or may be transmitted throughthe gear wheel l8, jack shaft 45,

- thereto a two part. clamp, one of the parts of' gears 46, verticalshaft 40 and pinions 38 and 39 to the shaft 30, from whenceit istransmitted to the feed roll. 6

Shifting mechanism is provided for controlling the engagement. of thepinions 35 and 36 and 3S and 39 and this shifting mechanism preferablyincludes a hand lever 50 pivotally mounted, as-at 51, to a bracket 52.The portion of the hand lever 50 pivotally 'mounted on the bracket hassecured thereto and movable therewith a-lateral arm 53 upon which aweight 54: is adjustably mounted. In order to provide forth'e connectionof the hand lever to the hub 37 and consequently to the sleeve 32 acollar 55 is loosely mounted in the annular groove 37 and has securedthe clamp 56=carrying a lateral pin 57 which is fitted-in an opening-58provided therefor in a hand lever 50; The arrangement is such that thegears 35 and 36 may be disengaged by a manual shifting of the hand lever'50 and of course. by such shifting the gears 38 and 39 are engaged butwhen however the gears 38 and 39 are'to be disengaged and the gears 35and 36 engaged the operation is entirely automatic. For this purpose thelever 50 has fixed thereto a spring dog 60 cooperable with teeth ornotches 61 provided in an arm 62 carriedbythe frame extension. As shownin Fi'gure 6 the notches 61 have inclined faces 61 and vertical faces 61so that the lever may be shifted to the left as viewed in Figure 3without interference from the spring dog since it snaps over theinclined walls 61 of thenotches. Reverse movement jof-the lever, that isa movement fromyleft' to right, as viewed in Figure 3- can only be hadwhen the spring dog 60 has been pressed away from the arm 62 and therebywithdrawn from the notches 61.

Automatic tripping or releasing mechanism',-,is provided for releasingthe spring dogl60 that is for retracting it from engage ure 3. -Thisreleasing mechanism includes a shaft 65 rotatably 'mounted in bearingsprovided on the frame extension and arm 62 and having fixed to one end.thereof a large gear wheel 66 meshing with a small gear wheel 67 fixedon'a oountershaft 68 rotatably mounted on the frame extension. Thecountershaft 68' also has fastened thereto a large gear wheel 69 withwhich a small gear wheel 70 fixed-to the sleeve 32 is adapted to engagewhen the gears 38 and 39 are engaged and the gears'35 and 36 aredisengaged that is when the gears are shifted to the left as viewed inFigure It is to be'noted that the gearing between the pinion 70 (whichbeing fixed to the sleeve 32 is thus indirectly fixedly connected tothe'shaft 30) and shaft 65 'is'of such ratio as to very materially.re=

duce the speed of the shaft 65 with respect to the shaft 30 so that theshaft 65'turns very much more slowly than the shaft-3O and consequentlyvery much more slowly than the feed roller. In order to permit of thenecessary variation in the relative speeds of the shaft 65 and the feedroll the countershaft 68 is mounted in an adjustable bearing in theframe extension asindicated at 71, in

Figure 4: so that various sizes of gears 67' and 69 may be employed. Acam is loosely mounted on the shaft 65 and includes a lateral andlongitudinally extending finger 76 at its periphery engageable with thespring dog 60. An actuator 77 is'provided for the cam and is secured tothe shaft 65 by a set screw 78 and is provided with a laterallyextending pin- 79 engageablewith the cam 75 to rotate the same with theshaft 65. The cam 75 is held against longitudinal displacement in onedirection by the actuator 77 and is held against longitudinaldisplacement in the opposite direction by a collar 80. 'VVith thisarrangement the shaft 65 and consequently the shaft '30 and feed rollcan partake of considerable'rotation while the feed roll "is beingdriven independently of the doffer through the gear wheels 38 and 39 79engages the cam 75 to rotate the same and the cam can be so located onthe shaft relatlve to this actuator that it passes through a part or thewhole of another revolution be- ,fore its. pm 76 presses against thespring dog 60 to retract the same and permit the weight.

5 1 to disconnect the gear 38 from the gear 39 and to bring the gears 35and 36 into mesh and thus to drive. the feed roll. The disengagement ofthe gears 38 and 39 is accompanied'by the disengagement of the gears 69and 70 since the gears 70 and 38 are carried on the same sleeve.

Braking mechanism is provided for stopping the shaft 65 as soon as thepinions 69 and 70 are disengaged and thus holding the cam and itsactuator in its proper position ready. for the next operation. Thisbraking mechanism includes a braking element 85 slidablv mounted on thearm 62 and connected to the hand lever 50 by its apertured lug lug 86.Nuts' 88 areithreadedly connected with the rod 87 andengage the lug 86onthe opposite sides thereof whereby adjustment may be made to secure.the desired degree of braking action and to compensate for wear.

When' it is desired to carry out the stripping operation the hand lever23 is raised so that the swinging arm :21 is lowered and the pinion 18is disengaged from" the gear.

.uWllBBl 17 of -the defier whereby' the-feed roll is stopped since thedrive is transmitted to the feed roll through the dotl'er in the normaloperation of the machine. When the dofler is being stripped the handlever 50 is moved to the left, as viewed in Figure 3, and is engagedwith the middle notch of the arm 62, the spring dog 60 looking the arm50 in such position against retrograde movement. lVhen the strippingoperation has been completed and normal operation of the machine is tobe resumed the hand lever 50 is shifted to the extreme left handposition as viewed in Figure 3 so' that its spring dog 60 engages in thethird notch 61. This shifting of the arm 50 brings the gears 38 and 39into engagement so that the feed roll is then driven from the pulley 25through the gears 18 and 48, jack shaft 45, beveled gears 46, verticalshaft 40 and beveled gear Wheels 38 and 39. The feed roll then operatesto feed the cotton to the main cylinder but the doffer is not operatedto take the cotton from the cylinder at this time. Moreover when thefeed roller is so operated it is moved very slowly for it is beingactuated through the speed re duction and thus the cotton is fed at alow rate of speed into the card so that the card has more time in whichto spread the cotton into an even sheet adapted to uniformly charge thecylinder. During this time the shaft 65 is also being driven though moreslowly than shaft 30 and the cam actuator 77 is being rotated aroundinto engagement with the cam so that subsequently and at a time when themain cylinder has been properly charged the cam will be actuated and itsfinger 7 6 pressed into engagement with the spring dog 60 to move thedog out of its notch 61 thereby releasing the lever 60 and permittingthe weight 54 to move the lever 50 and consequently the sleeve 32 to theextreme right as viewed in Figure 3 so as to bring the gears 35 and 36into mesh and so as to disengage the gears 38 and 39. The hand lever 23is then lowered to raise the arm 21 and move the pinion 18 out ofengagement with the pinion 48 into engagement with the gear wheel 17 soas to drive the doffer from the pulley 25 and drive the feed roll fromthe doifer as in the normal operation of the device. With thisarrangement the carding machine may be stripped as often as founddesirable and at the same time a high grade product is obtained for thesliver is of uniform and requisite weight and quality. A guard for thegears .69 and 66 is mounted on the bracket 43.
